Yesterday’s taste of summer weather gets replaced by a nicer, late spring type of day today as a cooler air mass slowly works into the region. Gone are the 80s and in are the 70s under mostly sunny, but breezy conditions. The breeze and dry air mean there’s plenty of pollen in the air.

We drop another nearly ten degrees tomorrow with clouds and highs in the 60s. Thursday and Friday are nicer with warmer weather, but a slow-moving storm system is aiming to cloud up later Saturday all the way into Sunday, while delivering some much-needed rainfall to the region.

Today (Tuesday Tax Day): A dry cold front came through overnight to change our winds and adjust our temperatures lower. However, mid-70s today and mostly sunny skies still offer a nice, warm feel. Unfortunately, the humidity plummets this afternoon, so those breezes of 10-15 mph from the northwest blows allergens around on us. Confidence: High

Tonight: Clouds return as a disturbance approaches the area. Lows drop into the upper 40s in the outer suburbs to the low-to-mid 50s in the city. Light winds. Confidence: High

Tomorrow (Wednesday): Cloudy skies and cooler temperatures dominate this middle day of our work week with highs only in the mid-to-upper 60s. The main bulk of this disturbance should pass to our south, but a 30% chance of mainly afternoon/evening light showers exists. Confidence: Medium

Tomorrow night: Partly to mostly cloudy skies with still a 20% chance of an evening shower. Lows should drop into the 40s in most areas, but the city may hold around 50. Confidence: Low-Medium

A LOOK AHEAD

Thursday is partly cloudy in the morning and then mostly sunny for the rest of the day as temperatures rebound to the upper 60s and lows 70s. Lows Thursday night drop to the upper 40s and low 50s under partly cloudy skies. Confidence: Medium

The weekend outlook may be controversial as those with outdoor plans would rather the weekdays be watered instead. But we desperately need rain in these parts, so the arrival of a slow-moving storm could be great news for parched vegetation and the purging of the pollen. The latest guidance suggests increasing clouds on Saturday with highs in the middle 70s. Showers and maybe thunderstorms work into the area Saturday evening and overnight (lows in the 50s) with more rain during the day on Sunday as high temperatures manage to get no further than the mid-to-upper 60s.

These latest trends for a slow-moving system could deliver heavier precipitation totals, but we need to watch exactly how this scenario unfolds closely in the coming days. Confidence: Low-Medium
